Hello,
first, be sure you run latest version of branch 4.3, there was a fix for
dialog since 4.3.2.
If a process in shown to run recvfrom() that means it waits for kernel
to pass a new upd packet to it -- recvfrom() is a function from standard
lib c.
Wireshark (like other sniffing tools) is capturing the network traffic
before the kernel passes it to application layer. If wireshark see it,
doesn't mean the application has received it from kernel, it can still
be dropped by firewall or other kernel modules.
You can add a xlog() at the beginning of request_route to see what
requests are received by kamailio.
Cheers,
Daniel

Hello Danel,
Thank you for your response,
Well i don't have SELinux enabled and IPTables isn't running.
About kamailio configuration, Pike module isn't also enabled, the only
thing that i have enabled to limit the number of concurrent calls is
the dialog module, counting the number of active dialogs and reject
next new invites only after it has reached the 10.000 simultaneous calls.
The strange behavior is that kamailio only stop processing some sip
messages like Byes and 200 Ok after more or less 40 seconds after
siptester start sending calls.
And i can see several cases in wireshark that kamailio receives
BYES/200OK from interface B(Carriers interface) but it isn't forward
to Interface A(customer interface), if i make for example 20cps i
don't have this issue, all packets are handled correctly and there
isn't 408 requests timeouts.

The tmp variable is not intialized by default, so it can be
anything therefore the out of bounds value. It used only when
printing some errors, so it didn't get a proper value as no such
error was printed for you case.
The backtrace shows the process in in recvfrom(), so it waits for
traffic from network. That is the case when the processing of
former sip message was finished and now Kamailio waits to receive
another one.
If you run centos, be sure you don't have limits in selinux rules
- better disable it completely and test again. Also, be sure you
don't have limits in the firewall, especially contrack module and
sip firewall modules in the kernel.
In kamailio.cfg, if you have pike module, be sure you don't drop
good packet with this module.
Cheers,
Daniel

Adding more information to my last email,
when kamailio starts
receiving calls, after more or less 40 seconds it stops
processing some sip messages.
I'm using the kamailio version 4.3.2

I have one kamailio server listening in 2 network interfaces,
kamailio receives sip messages from interface A and then send
it to destine through interface B.
When we start kamailio service then run gdb for each
kamailio network interface process, execute the command "bt
full" the result is the following:
